Media company Star India acknowledged Friday that it was the source of the leaked episode and said it is investigating how it happened.

The news comes just days after HBO said hackers had broken into its systems and stolen "proprietary information." HBO, however, said that Friday's leaked "Game of Thrones" episode was not a part of that hack.

Episode 4 of the show's seventh season is due to air Sunday.

Star India, a subsidiary of 21st Century Fox, reaches more than 700 million viewers a month across India and more than 100 other countries.
